30K hours -> nearly 3.5 years at 100% duty cycle. If you "only" use your computer/TV for a few hours a day, that shouldn't be a problem at all. If you use it all 24/7, then maybe it's not the best solution.

The problems with LCD and Plasma are different.
Plasma can suffer from burn-ins simply because the high temperature. The layer (whatever material is used) can be "burned" with the pixels, thus always displaying them.
For LCD, it's different. They mostly suffer from "ghosting," since they build from liquid crystals. These crystals has to align to let through or block light to the screen, thus creating the image. If they crystals can't realign fast enough, you get some parts from the previous frame and some from the current, which is known as "ghosting."
Still, many of today's TVs don't have either of these problems.
Oh and LCD TVs may require replacing the back lightning bulbs if they break and it costs a fortune. But neither my LCD TV nor computer screen has required such a thing yet.

As for that, LCDs and Plasma how about the same life length I think.

I've had the backlight inverter replaced on a monitor. It's wasn't that expensive, maybe $60 for the part and $40 for the install, and replacing the bulb would be even cheaper (though the bulb is rarely the problem). You can even do it yourself if you're kind of handy. A large screen TV may be a different story, though.

Have you considered waiting for a 'digital projector' or whatever they're called?
I've heard about them, just as good as the analog projectors, except there's no globes that die every 100 hours or whatever.

Once again, Urban myth or truth -- Only research would give the answer.

That will probably cost even more.
It's best not to buy the newest advancement in science since it's usually not worth the cost.
But even so, there's another question: which one is best - TV or projector? :)

In terms of what? Picture quality? If that's what you're asking then the answer is projector, by far. Could I tell you why? No. However, I know plenty of video experts that would agree unanimously on that statement.

However, if you're asking about cost and maintenance, then the answer is TV. And by that... in my own opinion, overall TV is better for any kind of home theater because I, like most, don't have time for the maintenance that projectors require.

Indeed, and as we see, there is a heated discussion there, as well.
You'll have to take factors into mind to have a proper place to project the image, as well, for example.
So it depends on if you want a projector really...
